__assert_fail

Name

__assert_fail -- abort the program after false assertion

Synopsis

void __assert_fail(const char *assertion, const char *file, unsigned int line, const char *function);

Description

__assert_fail receives a string containing the expression assertion, the filename file, and the line number line, and prints a message on the standard error stream. For example:

a.c:10: foobar: Assertion a == b failed.

__assert_fail then aborts program execution via a call to abort. The exact form of the message is up to the implementation.

If function is NULL, then omit information about the function.

assertion, file, and line must be non-NULL.

__assert_fail is not in the source standard; it is only in the binary standard.
